It’s that time of year again. The days are shorter, the nights are longer and 5 p.m. looks like 3 a.m. Our circadian rhythms are all out of whack. All we want to do is hibernate.

That said, if you’re going to go to bed at granny hour, why not make the most of your time spent under the covers? Now’s the time to indulge in some cold-weather-fighting overnight beauty products that will ensure you wake up looking — and feeling — well rested, rejuvenated and ready to seize the (abbreviated) day.

After all, skin repairs itself at night. Per Kendra Flockhart, education executive at Darphin, “All day, skin works hard to protect itself from constant attack but while we’re sleeping, skin switches into ‘recovery mode,’ a time of intense repair and regeneration. In fact, at this time the regeneration process can be up to three times faster than during the day.” During the nighttime, in addition to being more active, skin also becomes more permeable. Products are more readily absorbed. On the flip side, water is more easily lost. Thus, as always, what we choose to put on our skin is key.

Above, you’ll find 12 hydrating, easy-to-use products you can use before you hit the hay to maximize your (literal) beauty sleep. From a no-rinse-required hair conditioner to all sorts of sleeping packs (K-beauty for the win), these nocturnal treatments will (hopefully — everyone’s body is different) solve your beauty woes overnight. Sleep tight.
